Publish Android Test Page

This page automatically builds the Android app from the latest commit on
the branch master, generates a test page and publishes it to GitHub
Pages as a nice way for non-developers to get the latest app version for
testing without having to build it themselves.

This page might need the pages source set to GitHub Actions at
Settings → Pages → Build and deployment → Source.
